Samsung has revealed it will be expanding its Galaxy family of Android-powered smartphones with four new handsets.

The Samsung Galaxy Ac,e which will be exclusively available in the UK on mobile network 3 later this year, will be joined by the Samsung Galaxy Fit, the Samsung Galaxy Gio and the Samsung Galaxy mini.

The Samsung Galaxy Ace is being billed as the successor to the Samsung Galaxy Portal and benefits from an 800MHz processor along with a 3.5in 320x480 touchscreen display.

The sleek black handset also comes with Version 2.21 of the Google Android OS, known as Froyo, along with a 5Mp camera, GPS and Wi-Fi connectivity. Furthermore, the smartphone can be used as a Wi-Fi hotspot and allows other devices such as tablet PCs, laptops and games consoles to connect to the internet via the phone.

"We're delighted to be bolstering our handset portfolio with this new device," said Sylvia Chind, head of branded devices, at 3.

"Doubling up as a personal Wi-Fi hot spot, the Samsung Galaxy Ace offers unique smartphone functionality and our customers can use Three's high speed 3G network to enjoy Google Maps, social networks, downloading apps, shopping online and much more."
